I just recently took a trip to Virginia. TT got me there just fine, but when we decided to go to DC, WOW. TT didn't even know of half the roads there. Some of them didn't even exist anymore. TT told me to take next right, but there was no exit there anymore. On screen it looked like I was driving in the dirt a lot of times. I'd hate to take TT to Boston W/the big dig. I really hope the Map updates come out soon.
